WILLIAM P. LARGE, OF CHICAGO, ILLINOIS.

LAUNDRY WASHING MACHINE.

Application filed May 14,

My invention relates to that class of laundry machinery wherein washing is done in lots or batches, each customers lot of washing being washed as a unit by itself,

and the object of my invention is to provide a holding means for a bag or other identifying piece connected with each separate lot or batch of washing, and this system is employed chiefly in what is termed the wet H1 wash system, or may be employed inany system.

The custom to which my invention chiefly relates is that wherein the soiled goods are brought to the laundry in a container, usually. in the formof a bag or sack or-wrapper of cloth, and the identification is 011 this bag only and the contents of the bag is discharged into the washing machine and the bag along therewith and thus thebag itself:

becomes the identifying feature of that particular lot of wash.

In the handling of these lots. or batchesv of washing in a commercial laundry the washing machine is divided into compart ments and each compartment. is to contain only a single batch or'lot of washing for any given one customer. The wash must be discharged from the bag or container in order to wash properly, then the 1 bag itself is. washed along with the goods.

In the washing operation the bag and the other goods that are being washed become very much intermingled and on the opening of the washing machine on the completion of the washing much time is lost by the operator in pawing over the wetclothes to find the bag, into which that particular lot. is again placed as it is removed from the washing machine. 1

It seems that the bag has a preference of hiding itself under a mass of the other goods, which requires the operatorto spend con siderable time infishing it out, and the object of my invention is to fix a specific loca: tion for this bag on the inside of'the washing. machine in away that the operator may at once find it andsave time in gathering up that particular'lot out of the washer.

Perhaps I might term that my inventionv consists in a bag or container holder provided for the inside. of the washing machine. This holder must permit a full and free wash of the bag itself aswell as to hold it in a definite position, alwaysv accessible to the operator.

Reference will be had to the; accompany 1924. SerialNo. 713,177.

In the drawing 1' indicates the leg or supporting members-of an ordinary drum washing machine and 2 indicates the outside drum of closure for the machlne.

cylinder 2. there is the washing drum.5 and this drum is usually a perforated drum which allows the washing water or1fiuid,.perhaps better understood as the soap suds, to freely circulate through the walls of this revolving form 5. The drum 5 is provided This is. a closed cylinder water-tightand having. a door opening at one side as indicated by 3.

On a shaft 4 mounted on the inside of the with suitabledoors for opening and closing the drum 5 and these doors are indicated 6. In a machine of the class described in which my invention will be used, the drum 5' is divided into. as many compartments as may be desired for the class of work with which it is used, and this is accomplished by suitable partitions and one of these partitions is indicated as 7 in Figure 1. I

My invention'broadly consists of a bag holder or clasp device or any suitable device that will hold the bag within the cylinder I 5 in easy access of the opening covered by the door 6. It is not only essentia-l'that this bag holder. should hold the bag in place, but

should hold it in a manner to allow it to v be suitably washed and it may be of such character as to permit a quick and ready placement of the bag within the holder and correspondingly a quick and ready release and at the same time it should be adapted to take bags of varying thickness and Varying degrees of careless handling in the way of overlapping of. portions of the bag itself so as not to require too'much time of the operator in fixing the bag in the holder.

quickly insert the bag and quickly remove the same and that the bag will he held by an elastic connection or an adjusting means that will lit dil't' erent sizes and manner of in sert-ion of bags. The location or this bag holding device may be varied more or less to suit the ideas of the users or 1711910111101 the machine in which it is used. This holdor may be secured to the cndsb or division walls 7 or the washer; or it may be secured to thelongitudinal members or to the door or gate of the washing drum or partly on each as desired. In Figures 1 and 29 indicates one location of my holder on the end 8 of the washing drum. Figure 1 10 indicates the position of the holder when fastened to the gate or door 6 of the drum or compartment. The bag hold-- er used in these positions'may be that shown in Figures 4, 5 or 6, or'any form meeting the requirements as I have described. Figures 9, 10, 11 and '12 relate to holders that are associated with the door or gate 6 in a manner to use the door asa part of the holderfitself. l

. The form of my holder which is shown in elevation inFigure 6 consists of a bed plate 11 secured by screws 12 to a suitable member of the washing drum indicated by 13. Thisholder is composed essentially of agripping jaw 01' lever 14 provided with I serrated or toothed edge 15 adapted to engage the bag 45 111 a secure manner in conjunction with a fixed jaw 16 of the bedor frame piece 11.. The jaw 14 is hinged by hinge pin 17 to the lugs 18 of the base piece 13, audthe jaw is provided with a bell crank lever arm 19 adapted to be engaged by sliding block 20 located in a guideway keeper pocket 21 in the base piece 11 in which there is mounted a coil spring 22 threaded over a guide stud 28 and adapted to push the block 20 against the bell crank lever armll) so that normally the spring 22 holds the jaw 15 firmly on the bag when the same is in place in the holder. A'hand hole 24 in the jaw 14 provides for the hand grip25 which gives the 0' erator freedom to lift the jaw 14 against tie pressure of the spring 22 and insert or. remove the bag as sidewise by the flanges 26, which take some of the side thrust load that is put on the jaw 14 from being transmitted entirely to the hinge pin 17 as in the use 01 this holder the wet clothes will exert severe strains topull the bag loose from the holderas the wash i-ng machine is revolved.

Another suitable form of my device is shown by Figure 4 in whichI provide the clamping j aw 27 having a similar toothed or serrated edge 28 to that. of the edge 15 of Figure 6, and this jaw 27is provided with a top flange member 29 by which the op erator may grasp the jaw in moving it as desired. This jaw 27 is hinged at 30 to a stud 31 seated in a pocket in a projection 32 of thebase member 41 and threaded through a spring 33 and abutting on a shoulder 84 in the projection and the stud 31 is secured to be acted on by the spring by a cap 35 held in place in stud 31 by screw 36, thus the jaw 27 may be raised andlowered about the hinge pin 30 and revolved around the axis of the stud 31 as desired. end of the'jaw 27 is held inplace by a keeper block 37 in the form of a loop having the hole 38 large enough to allow one or two fingers of the operator to be inserted in this hole to operate the block in the function ofclamping the jaw 27 in place. This keeper block 37 is provided with a stud portion 39, which is held within a: projection 40 of The other.

the base member 41, the latter being secured threaded through a springi43 in like manner to the arrangement of the stud 31 and the ring portion 37 passes through a slot 44 in the portion 29 of the jaw 27 and this slot is a longitudinal slot wide enough only to prevent the loop portion of the keeper block 37 passing through in one position only and thuswhen the jaw 27 is to clamp the bag 45 against the jaw 46 of the base piece 41 the operator presses the jaw 27 home when the loop portion is. positioned to pass through the slot 44 and then he pulls the loop portion outward and gives it a quar ter turn which looks the piece 29 in place. holding the jaw 27 in spring or elastic contact with the bag 45. By. this arrangement the jaw 27 is provided with an elastic or In Figure 5 I show a slightly modified construction from that shown in Figure 4,

the gripping jaw being substantially the same as shown in Figure 4.

In Figure 5 the clamping jaw is indicated by; 48 and is provided with ahandle-portion 49 and suitablefteeth 50 and this jaw 48 is provided with a projection 51 which amounts to a hinge pin composed of a portion of the body of the jaw itself and this hinge pin is mounted in a projection 52 of the base 53, which is secured by bolts 54 to any suitable portion of the washer 55 and within the projection 52. and threaded over the hinge pin portion 51 there is a spring 56 held on to the projection 51 by a cap piece 58 secured in place by screw 59. In the use of this jaw 48 it is rotated about the axis of the projection 51 and withdrawn outward by compressing the spring 56 and thus by this rotating and withdrawing movement the jaw 44 is made to move to and from the fixed jaw 60'of the base piece 53 and the fixed jaw 60 is provided with theretaining teeth 61 in a similar manner to the other forms described.

The left end of the jaw 48 is provided with a rather short stud portion 62 (see Figure 7) which projects into a cavity into the outer end of a projection 63 of the base member 53 in which projection there is located a spring 64 having a cap 65 through which is threaded a screw 66 adapted to abut against the projection 62 outward in the release of the jaw 45 in the removal of the ba (The end 67 which carries the projection 62 of the jaw 48 is clamped and held in place by cam block 68 (see Figures 5 and7) having for its axis or hinge pin the screws 69 passing through the links 70 and the latter being hinged by the pin 71 into the base 72 of the base member 53.

A thimble 73 is passed over the hinge pin 71 and becomes the abutment against which the spring 64 acts. A lever 74 is provided with a loop end 75 and the other end 76 of this lever 74 is screwed into the cam block 68 and serves as a means of actuating the cam block in the release and fastening of the end 67 of the jaw 48. The drawings show the jaw 48 locked in position and when it is desired to be released from the bag 45 the loop end 75 of the lever 74 is pulled downward from the position of Figure 5 and thus releases the cam member or block 68 from the end 67 which permits the freedom of the spring 64 to push out the projection 62 and meantime the links 70 have been swung around the hinge pin 7] to pull off to the left the outer ends of the links 70 along with the cam block 68 to clear entirely the sweep of the end 67 of the jaw 48, which then may be rotated around the hinge pin center of the projection 51 of the said jaw 48 and thus release the bag from the jaws 48 and 60, the spring tension of clamping the bag in place being secured by the spring 56.

In the structure shown by Figures 9, 10, 11 and 12, the door 6 is made to cooperate 79 to a block 80 being a member of the washing drum itself. My device may also be sccured to any other suitable portion of the 7 interior of the drum of the washing machine. Fixed to the door piece 6' I provide the toothed jaw 81 having the teeth 82 and secured by the flange 83 to a filler block 84 to the lid portion 6 thus on closing the door from the open position shown in Figures 1 and 2 to a closed position as shown in Figures 11 and 12, the jaw 81 clamps the bag 45 on to the rod 77 and the spring or elastic tension being arrived at by the bending of the supporting flat spring 78. Suitable bolts 85 secure the jaw to the door piece 6. In the use of this form the bag is threaded through over the rod 77 and between the spring bars 78 a considerable distance to more or less balance the strains in the wash ing operations.

Another form of using the door as a cooperating member in holding the bag within the washing drum is provided by Figures 9 and 10 in which there is secured a block 86 by bolts 87 to the door piece 6 and the side 88 acts as an abutment or clamping member against the bag 45 which is clamped against the toothed jaw 89, having the pro jections 90 mounted in pockets 91 of a base member 92 secured by bolts 93 to the cross member 94 of the drum framing or in place of such a block as 94 being available then a smaller block will be provided for this express purpose of holding the base piece 92.

Springs 95 abut against the projections 90 and furnish the elastic contact of the jaw 89 with the bag 45 whenever the door 6 is closed to bring the portion 88 of the block 86 in contact with the bag.

In the use of this construction the bag will normally be trained up through the aperture 96 of the hinge region 97 of the door, thus the upper end of the bag will project out a little into the space outside of the revolving drum yet within the outer closing 01 the washing machine itself. The purposeof this is to serve as a temporary holder of the bag during the operation-of closing the door 6 because the bag will not be clamped by the closing of the door until the door is closed and thus a temporary means of holding the bag is thus provided by passing it through the aperture 96 and in this case the aperture 96 must always be made wide enough to accommodate the thickness of the ii the washing methods employed in which a bag or container of a batch of washing is used, the same method of keeping track of carrying through the batch is frequently used in a drying drum as well as in the washing suds or washing drum, as drying drums are provided more or less similar in construction to the washing drum wherein the clothes are revolved on the inside of V a chamber through which hot air or other combination with a rotary washing drum,

of a bag clamp provided with a; yielding clamping aw attached to an interior surface of said drum.

3. A bag clamp comprising a, clamping member having means for attachment to a door, and a co-operating clamping member having means for attachment to a doorframe.

4. In a device of the class described, the combination with a rotary washing drum provided with a door, of a yielding bag clamp having one member mounted on the inn-er surface of said door, and a co-aeting clamping member mounted adjacent to said door and-within said drum.

5. In a device of the'cla'ss described, the combination with a rotary washing drum provided with a hinged door, of a bag clamp having a member mounted on the inner surface of said door and a co-operating clamping member mounted on the inner surface of said drum, one of said members comprising a 7 base member provided with a pocket and a jaw member yieldingly mounted therein.
